Even if sec. 11 of CPC is not applicable in judicial proceeding, Principle of res judicata is applicable
The principle of res judicata is based on the need of giving a finality to judicial decisions. What it says is that once a res is judicata, it shall not be adjudged again. Primarily it applies as between past litigation and future litigation. When a matter-whether on a question of fact or on a question of law-has been decided between two parties in one suit or proceeding and the decision is final, either because no appeal was taken to a higher court or because the appeal was dismissed, or no appeal lies, neither party will be allowed in a future suit or proceeding between the same parties to canvass the matter again. This principle of res judicata is embodied in relation to suits in s. 11 of the Code of Civil Procedure; but even where s. 11 does not apply, the principle of res judicata has been applied by courts for the purpose of achieving finality in litigation. The result of this is that the original court as well as any higher court must in any future litigation proceed on the basis that the previous decision was correct. The principle of res judicata applies also as between two stages in the same litigation to this extent that a court, whether the trial court or a higher court having at an earlier stage decided a matter in one way will not allow the parties to re-agitate the matter again at a subsequent stage of the same proceedings.
